从波斯高原至青藏高原,是阿拉伯板块、印度板块同欧亚板块相碰撞的特殊地带。也是世界上最宏伟的陆内造山带。分析研究该地带的现代构造活动特点,将有助于研究,认识板内动力学及其地震成因。作者曾研究过我国及邻近地区的现代构造特征,新近又取得了波斯高原地区1968—1979年46次浅源大地震的断层面解结果(表1)。据此,结合地质和地震资料,探讨中南亚地区板块碰撞带的地质构造、现代构造应力场、现代构造形变和地震活动等方面的特征。
From the Persian Plateau to the Qinghai-Tibet Plateau, it is a special zone where the Arabian Plate and the Indian Plate collide with the Eurasian plate. It is also the most magnificent intracontinental orogenic belt in the world. Analyzing the characteristics of the modern tectonic activities in this zone will help to study and recognize the dynamics of the plate and the causes of the earthquake. The author has studied the characteristics of modern tectonics in China and its neighboring regions and recently obtained fault surface solutions of 46 shallow earthquakes of 1968-1979 in the Persian Plateau (Table 1). Based on this, the characteristics of geologic structure, modern tectonic stress field, modern tectonic deformation and seismic activity of the plate collision zone in Central South Asia are discussed based on the geological and seismic data.
